I sent the Publisher a note (I am one of their customers - I got a response:

 

Hi Harry

 

Thanks for bringing this to my attention, we're already looking into the issue and the cover art has been discarded. The book is one developed by one of our publishing partners rather than by our own team, so this issue slipped in without me noticing. It looks like the fault is with the cover artist for the Apocalypse book, and neither us or our partner company will use this artist again. Fortunately the book hasn't been printed yet, so it's an easy one for us to put right.

 

Thanks

Dom
